Compressors on the Edvard Grieg oil platform 160km from the Norwegian coast have been fitted with noise enclosures. 

These enclosures were designed and manufactured by Dutch company Merford Noise Control. The whole operation took a year to complete.

Aker Solutions in Norway commissioned Siemens in the Netherlands to develop the compressor skids for Edvard Grieg oil platform.

Siemens then assigned Merford Noise Control to develop high-quality noise enclosures for the compressors.

The new platform complied with all NORSOK standards of the Norwegian petroleum industry. NORSOK standards are applicable to every aspect of installation on the oil platform.

Siemens executive Mark Schreijer said: “For Merford, working with NORSOK was new. Fortunately, we knew what to do. From the very start of the project, we were both intensively involved in the design, production and all the other issues. This was absolutely necessary for the successful completion of this project.”

As pressing gas through the pipelines is a noisy process that can reach approximately 95 dB, the noise enclosures were required to reduce this.  

The Merford enclosures can reduce this noise significantly below the required level. Enclosures are also explosion-proof.

"The noise enclosures are designed in such a way that no parts can fly off."

Merford executive Stef Zoeteman said: “If there were to be an explosion on the platform, further escalations need to be prevented. The noise enclosures are designed in such a way that no parts can fly off, which as a result of the explosion, could lead to new explosions or calamities on other parts of the platform.”

Siemens and Merford designed the compressor trains to be unaffected by weather conditions.

The completely assembled enclosures were shipped on specially designed transport frames in 2014 to Norway. Structures carried a dimension of 16.8m in length, 5m wide, 5.6m high and weighing 34.2t.

Last November, the platform successfully started its operation.
